Systems and methods for intra-UE multiplexing in new radio (NR)
Methods and systems are provided for communicating in a wireless network based on a prioritization status. User equipment can receive a first signal that includes an indicator. The UE can determine a prioritization status for a second signal based on the prioritization indicator. The UE can communicate, with one or more radio access networks (RANs) of a network, the second signal, where the timeline of the second signal can be out of order respective of other signals communicated by the UE and the wireless network. The second signal can include data transmitted by an ultra-reliable low latency communication (URLLC) service. The UE can communicate the second signal out of order with respect to one or more additional signals. The UE, based on the indicator, can communicate hybrid automated repeat request (HARQ) feedback before a HARQ feedback timeline of a non-urgent transmission.
